The shoe base and drive lugs may be formed from a prehardened engineering steel, such as MECASTEEL 145. The wear plate may be formed from MECASTEEL 145 or an advanced abrasion-resistant steel, such as Creusabro 8000. The drive lugs may be replaceably attached to the shoe base, preferably by welding. The wear plate may be replaceably attached to the shoe base, preferably by fasteners such as bolts.
